Smucker's move comes as an increasing number of food makers have been lowering or eliminating trans fats from products. In December, New York became the first U.S. city to ban trans fats at restaurants.

Crisco's new formula uses less partially hydrogenated cottonseed and soybean oils and more fully hydrogenated cottonseed oil, which contains no trans fat.

Crisco still has a small amount of artificial trans fat, but the U.S. Food and Drug Administration allows any product with less than 0.5 grams trans fat per serving to list zero grams trans fat in its nutrition facts.
